Using GRC without UHD

GNU Radio
1

Hello GR,

Are there any fake sink and source blocks which simulates the uhd sink
and
source.
I would like to test some flow graphs but for the moment I don’t have
access
to the radios.

Or is there any other option, let’s say using a channel block between
the Tx
and the Rx.

Any hints or explanation are well appreciated.

Regards,
Ruecan

You can use file sinks- and sources. There’s also several different
channel blocks.

Thank you Martin,

Does the file sink and source blocks work in case of a stream of packets
(802.15.4).

In GRC, look under Channel Models for the available models we have in
the
code.

Connect up a null sink and null source in parallel with the uhd blocks.
Then right- mouse on the uhd blocks and select “disable”. This will
gray-out the blocks and not compile them, but will leave them there
preserving all your parameters.
